"My childhood was full of trapdoors and ejection seats instead of chutes and ladders".
I think that what OS needs is a script that will launch a chair and the sitter into the air like a fighter pilot's ejection seat. Sound effects - whatever we might imagine a chair like that sounds like when ejected, and some screams like what you'd hear on a carnival ride. The chair returns after a suitable time with the AV changed to look something like the post's image. The script should be able to be set to eject people randomly and/or in response to some trigger. I can supply the concept and the chairs. The rest I need help with. The AV switch will likely be the most difficult part to do.
I hope to use this in the Black Hole Dining Room in my club "Under The Overpass," currently under construction. Come see if you'd like.
